In reply to ewanjp: If you're going to Remigny then there are several places in the town where you can get the guide including the town hall, the noticeboard at the crag will tell you where. The JW guide misses out a lot of the routes at Remigny so I'd recommend getting that one.
You used to be able to get the Cormot guide from the guardian for the CAF hut in Vauchignon, you could call at the hut and see if anyone is about although the JW guide isn't too bad for Cormot. For a lot of the smaller crags I doubt there will be any separate guides.
For Saffres, as mentioned, the Tabac in Vitteaux sells it
